COMPOSITION ,SHINGLE.

Application filed September 17, 1926.

be laid in interlocked rows and with the lap portion of each shingle of any row interlocle ing with the underlying rows of shingles. In this manner the shingles are not only held firmly together in the rows, but the lap por tions are prevented from turning upwardly by the action of the wind, sun, or otherwise. A further object of the invention is to shape the shingles so that, when assembled, they will present a pleasing appearance. Other objects of the invention will be apparent from a con sideration of the accompanying drawings and the following description thereof:

()t the drawings Fig. l is a plan View of a sheet of shingle materialv showing how shingles which embody my invention may he cut from the sheet; Fig. 2 is a plan view oi: the shingles, slightly enlarged, as they. appear when laid on the roof; Fig. 3 is a plan view of a single shingle of this type; Fig. l is an enlarged sectional view along the lines44 of Fig. 8.

The shingle 30 of Figs. 1, 2' and 3 is of the general shape of a parallelogram. The sides of the shingle are more or less zig-zag shaped so as to form a hexagonal figure when the shingles are assembled. It will be obvious that by slight n'iodilicat-ions in the shape of the shingles these figures may be equiangular or equilateral, or both. The figure, however, is arrived at by forming a stripe 34 across the central portion of the shingle, as, in this case, the shingles are strip shingles comprised of what is equivalent to two individual shingles. its a consequence, there is no edge in this central portion and to give the hexagonal eltect the black stripe 3t is provided. Eachv of the shingles has a lug 22 on one side and a slit 23' on one end, the lug of one shingle being adapted to interlock with the slit 23 in the edge 2t of an adjacent shingle, in the same-horizontal row, so that the two shingles are more or less locked t()l;0tl1GI,' 1l1Ll'{Lt the same time the position of the shingles with reference to each other is determined. By so intcrlocle ing the shingles a row 25 is formed which ordinarily runs horizontally and which laps on an underlying row 26 of similarly interlocked shingles. Each of the shingles also has :1 lug 32 and a slit 3i and when assembled the lug 32 of a shingle in one row is passed upshingle.

'ardly through the slit 31 ot an adjacent shingle in the overlying row. in this instance the shingles are laid in longitudinal rows .35 and 26, and also in transverse rows 28 and 29.

The manner of cutting these shingles without waste is clearly indicated by Fig. l. A zig-zag line is-vcut longitudinally across the central portion of the strip o1 shingle material, and also a series of zig-zag lines are cut transversely of the sheet, the shape of these lines being such as to provide the desired shape of the shingles and also to provide suitable interlocking means. The angles formed in the transverse lines are approximately 120 so as to form angles of hexagonal figures, and the various straight portions of the lines are substantially equal. At certain corners the lugs and 32 are formed, as indicated.

As stated, these shingles, being strip shingles, comprise two individual shingles, and itbe omes desirable toindicate a central line so as to complete the configuration of the design. In this instance, I prefer to form ridges 33 across the shingles. These ridges are Formed. by forming ridge 33 therein as indicated in Fig. el, and on top of the ridge a strip of asphalt 34 is placed, thus forming a black stripe along the top of the ridge. In this manner a very clear line of demarcation is made along the central portion of the These ridges and stripes are preterahly formed in the sheets of shingle material before they are cut.

I claim as my invention:

1,. A shingle having the shape in general'of a parallelogram but with one pair of Opposite edges comprising sets of substantially equal straight portions angularly inclined to each other, a lug projecting outwardly from one corner of said shingle, and an interior slot in another corner of said shingle, the said lug of one shingle being adapted to interlock with theslot of a similar shingle whcnsaid shingles are assembled.

2. A shingle claimed in claim 1 and having a second lug projecting from the edge of the shingle between saitgl first lug and said slot and adapted to he slipped under the edge of a. third shingle when said shingles are assembled.

A shiugloas claimed in claim 1 and having a second lug projecting therefrom between said first lug and siid slot. and having a slit pro eet1ng inward/y from the end adjaeent to said slot, said second lug being adapted to interlock with the slit of a third shingle when said shingles areassembled.

4. A shingle having the shape in general of a parallelogran'i, aflug projecting outwardly in the plane of the shingle from one corner of said shingle, and an interior slot in another corner of; said shingle, the said lug of one shingle being adapted to interlock with the slot of a similar shingle when said shingles are assembled.

5. A shingle as claimed in claim 4 and having a second lug projecting therefrom between said first lug and said slot, and having a slit projecting inwardly from the end adjacent to said slot, said second lug being adapted to interlockwith the slit of a third shingle when said shingles are assembled.

1 Irl testimony whereof, I hereunto set my ian FRED n. THEILACKER.
